[BioC] human miRNA predicted/validated targets

[Ranjani R [guest]]

Hi,
I am hoping to find an R package/downloadable resource for validated (and predicted) miRNA targets. I have already investigated a few sites : miRWalk (which is not downloadable in its entirety and has a limit on the number of miRNA you can feed into it's web form), tarBase (which does not seem to have been updated in a while) and miRecords. miRecords does have a downloadable excel spreadsheet with validated target information (and pubmed ID) - and has 2112 miRId -> Gene pairs.
Which is usually the methodology of choice for working with predicted/validated targets? I am concerned with using resources that may not be updated regularly -- or in downloading a file which may be a snapshot at a certain time.
Any guidance would be greatly appreciated.
Thanks,
Ranjani
